Fiber Coupled Blue LED for Optogenetics experiments in Freely Moving Mammals
The Prizmatix Optogenetics-LED-STSI module is specially designed
to provide Optogenetics Stimulation / Silencing to the same neural structure
in freely moving mammals. The device combines two LEDs of different colors
into same single output fiber. Each LED has independent power and switching control.
The wavelengths combination can suit widely used Stimulation and Silencing opsin pairs,
ChR / ArchT, ChR / C1V1, ChR / EnpHR3.0 be Blue / Green, Blue / Yellow and
Blue / Red and other wavelengths upon request.
The Optogenetics-LED-STSI based system enables bilateral activation / inhibition
with single device and single one-channel rotary joint for
significant cost saving and without compromising power at implant tip.
Dual / Single fiber and fiber optic cannula (implant):
Optical Power from 200μm cannula
Optical Power from 250μm cannula
Optical Power from 500μm cannula
Irradiance from 200μm cannula
Prizmatix‘s unique large emitter LEDs enable
bilateral stimulation with a single low cost light
source and simple one channel rotary joint.
Using a simple Y-shaped fiber bundle at the rotary joint
will double the amount of light delivered to the brain
each branch delivering virtually the same power as a single fiber.
This results in significant cost saving in setting up bilateral
brain activation and silencing systems, compared to alternative light sources.

We offer DIY cannula components
such as high NA fibers and ceramic ferrules for online purchases.
Prizmatix Rotary Joint is
especially designed for Optogenetics experiments
with High NA fibers equipped with FC connectors.
Rotary Joint very low friction and smooth swivel operation are demonstrated
in this video - showing continuous rotation for over 30 seconds after a
The torque required for free movement is very low thus reducing
the Rotary Joint's behavioral effect on freely moving animals.
Prizmatix Rotary Joint can be used with large core input optical fiber connected
to several thin output fibers simultaneously. This allows concurrent delivery of light
to separate areas of the brain without loss of power due to the fiber split. See more..
Prizmatix Implantable Fiberoptic Cannulae / Ferrules
allow direct light stimulation of certain deep brain regions
in living animals.
Each Cannula consists of a Zirconia ferrule
accommodating a high NA Silica optical fiber, protruding from
the Zirconia ferrule at a desired length. See more...
Prizmatix provides a full solution to the optogenetics
in vivo and in vitro fiber optics. Made of silica or polymer fibers,
the high NA fibers are assembled to fit any research set-up with various
combinations of connectors, ferrules, core diameters and lengths.
Some examples are Y-shaped fibers for simultaneous in-vivo
stimulation of two hemispheres, and fibers with stainless steel tip
with protruding bare fibers for in-vitro activation of brain
slices under a microscope. See more
Prizmatix offers a wide range of standard and
customized multi-mode silica / polymer fibers as well
as ferrules for optogenetics research.
A Y-shaped fiber bundle is especially useful
for activating two brain hemispheres simultaneously:
a 1000μm or 1500μm fiber is coupled to the LED and
connected to one side of the Rotary Joint.
From the Joint’s other side emerge two thin fibers which can
then be connected to two separate ferrules: the light from
the LED is divided equally between the two hemispheres
without any loss of power.
